Pursuant to 10 CFR 21.211d)(4), ESI is presenting the required information as follows:

(i) Name and address of the individual or individuals informing the Commission.

(ii) Identification of the basic component supplied within the United States which fails to comply or contains a defect.

EMO Cylinder Uner, PIN 9318833, SIN 20D6294 Component of Blade Power Pack Assembly, PIN 40124898, SIN 20L0603

(iii) Identification of the firm supplying the basic component which fails to comply or contains a defect.

Engine Systems Inc. (ES/)

(iv) Nature of the defect or failure to comply and the safety hazard which is created or could be created by such defect of failure to comply.

An EMO cylinder liner developed a jacket water leak following installation on an emergency diesel generator set. The teak occurred at a brazed joint and was detected after post-installation engine testing. Had the leak gone undetected, jacket water may have accumulated in the combustion chamber or airbox and potentially contaminated the engine's lubricating oil. Jacket water intrusion into any of these areas is undesirable and could lead to failure of the diesel engine and therefore failure of the emergency diesel generator set.

(v) The date on which the information of such defect or failure to comply was obtained.

February 22, 2024

(vi) In the case of a basic component which contains a defect or fails to comply, the number and location of these components in use at, supplied for, being supplied for, or may be supplied for, manufactured, or being manufactured for one or more facilities or activities subject to the regulations in this part.

The extent of condition is this single cylinder liner, PIN 9318833, SIN 20D6294 used in the power assembly shown below.
